At the macroscopic level that’s familiar to us, birds chirp, whales sing and we talk. But at the microscopic level, our cells pulsate, bacteria swim and pressure waves ripple on a scale we can’t reach.

UC San Diego engineers have developed a tool to access that realm: an optical nanofiber that deforms in response to ultra-minute forces, sending patterns of light detectable by a microscope.

With this device, subtle motions of cells associated with biological processes, said Donald Sirbuly, a UCSD nanoengineering professor who led the study that created the instrument. These potentially include motions pertaining to cancer and stem cell development.
